Someone told me that it is best when sailing to leave the engine in reverse because when the water passes by the prop, it spins the prop, thereby moving the gears and creating more wear and tear on the gears, unless the engine is in reverse, true?

I understand that is true
If you have a hydraulic transmission (like mine) then reverse is where you want to be. My feathering prop will spin in either neutral or forward and will obviously not feather. If I shift into reverse, the prop and shaft stop instantly. My previous fixed prop would acted the same. If you have a mechanical transmission, then either forward or reverse will work to stop the prop, shaft, and gears from spinning. Yes, I agree that these rotating parts would suffer more wear if they are allowed to spin. Also noisy too. I have also heard that heat is a factor since the transmission is not cooled with pumped water like it would be if the engine were running. I can't confirm that this is a real concern. Rich

Check the archives.
Janet: There has been several discussions on this over the last couple of years. You really should review the archives and read all the articles about it. We are only running a fixed 2-blade prop and if I hear the prop turning I put it in reverse, otherwise I just leave it alone. From the input that everyone has posted, I think it is probably a good idea. Does not apparently cause any problems if you do it, so why not.

most definately
after a $720 rebuild the answer is yes the repair shop told me that you have no lubrication if the input shaft is not turning . i had to replace all the clutches in mine.

shifter locks up
I put the shift in reverse while underway and could not get it back to neutral without starting the engine. Is this normal?

ruins clutch
The problem with the spinning shaft is that the clutch plates will polish and wear. Lubrication of the gears running in their oil bath is not the issue. The clutch will become worn out and ineffective, thus causing the rebuild. If you read the owner's manual for the Universal MX25 (for my C30) it tells you to put the transmission into reverse while sailing with the engine shut down. Tech Talk from the C30 association also has lots about it..

Terry Arnold wrote an excellent post on this subject which is in the photo forum dated 2/6/00 titled "sail with *GM tranny in forward?, reverse?, neut.?" in which he explains why the tranny should be left in reverse. Most posts by people that seem to have some knowledge about this issue have come to the same conclusion. That being said, my transmission also locks in reverse. It is impossible to shift it out of reverse if I'm going faster than about 1/2 knot. Usually I bring her up into the wind to stop forward movement, but on occassion I have started the engine in reverse, immediately after which I am able and do shift to neutral. I hope I am not destroying my engine when I do this, but I don't hear any grinding or banging so there is immediate catastrophic damage. If someone can shed further light on this issue (starting in reverse) I'd appreciate it.

Reverse...However....
Every boat I have owned, I would have to start the engine while still in reverse. I could never get the gear shift out of reverse otherwise.

sail in reverse? Yes
Talked to the Yanmar rep at the Sail Expo in Oakland, CA. He said yes to sail in reverse. John
